My Civic has for the most part performed excellently over the years. But it is now at 105,000 miles and I am doing a lot of driving now (between 2-3,000 miles per month). I really want to essentially drive this car into the ground before I have to buy a new car and am wondering if I can get some advice on oil changes. So there are a few questions here,
- First is whether it is more beneficial for me to switch to a synthetic rather than the 5w20 conventional oil I have been using? If so would I really be able to go 15,000 miles between oil changes or no?
- Second, is whether it is worth it for me to perform the oil change myself or to go to Honda to do it? This goes to both price and the additional checks that Honda does when you bring in the car.
- Finally, I was reading about the differences between oils and am not completely sure if there is a difference. But if there is, would people recommend switching to the high mileage oil at this point (I don’t know if that matters with synthetics or not)? And also switching to heavier 10w30 oil? I live in Minnesota so while it is warm now (finally!), I know that won’t last long and it will be cold again. I had read that once you switch to heavier oil you should switch back so would switching to a heavier oil be a bad idea?
I know there’s a lot here I’m asking so thank you in advance for helping me with these questions.
